Both players have tasted little to no action over the past six months to a year, with Phala having been released by SuperSport United in March and the Botswana international having been left on the fringes at Mamelodi Sundowns.
Nonetheless, their wait for game time is expected to end following their capture by Lidoda Duvha.
Leopards will hope for an improved performance next season after securing their place in the top-flight, finishing 13th on the league standings.
However, they will be without head coach Dylan Kerr who masterminded their escape after he resigned from his post at the end of the previous campaign.
Meanwhile, a lot will be expected from the duo who possess an abundance of experience.
The midfield pair have represented their respective nations and have tasted adequate success.
Phala managed just six league appearances for SuperSport before his departure while Ngele did not make a single appearance during Sundowns’ successful defence of their PSL title.
Despite the latter having been signed as one of the league’s most promising players back in 2015, he failed to hit the heights expected from him.
Ngele made just 11 league appearances for the Tshwane giants and he will be keen to rediscover his best form which saw him shoot to stardom at Platinum Stars.
